[U-Boot-Users] MPC8343 I2C problem

[Monstr at seznam.cz]

HI,
I am trying to port U-BOOT to board with MPC8343 and I have problem with reading data from I2C. Iprobe command  detects EEPROM memory  but after imd 50 0 20 a read only 0xff values. In EEPROM memory is stored configuration words. And configuration word is strored properly because after unplug BDI board starts fine and we can reading memory via OS. I tryied to change SPEED too.

Best regards
Michal Simek
